.Specification forming part of Letters Patent No. 201,670, dated March 26,1878; application flied 4 l January 14, 1878.

To all whom 'it may concern: i

Be it knownA that I, HORACE L. HEWITT, of Alton, Madison county, in the State of Illinois, have invented certain new and useful Improvements in Sulky-Plows, of which the following is a full, clear, and exact description,

reference being had to the accompanying drawings, forming part ofl this specication.

the pivot-bracket of the plow-frame. Fig. 5`

is an enlarged perspective view of the arched axlebar, with the malleable cast-iron brackets or clips for connection of the crank-axle, tongue, plow-bail, and front foot-bail, and seat.

A is the near or land wheel, and B is `the off or furrow wheel. The land wheel turns on the spindle c of the axle-crank (l, and the bearing-pin c' of said crank turns in a bearing-bracket, D, made of malleable cast-iron,

and formed to fit the end of the wrought-iron axle-bar E, to which it is connected by bolts or rivets.

Upon the bearing-pin c is fixed a lever, F,

which works on the side of a semicircular plate, G. The plate G has a series of perforations, g, concentric with the pin c.

H is a spring-catch lever, at whose lower end is a pin, h, passing through the lever F, and through any one of the holes g formed in plate G, according to the positionof the lever. The position of the lever governs the position ofthe spindle c of axle-crank, and consequently the height of that end of the axle-bar E from the ground.

I claim no novelty in this axle-crank C, as it has been in use for a number of years and is well known, and therefore will not further describe its construction or purpose; but I claim novelty in the manner of its connection to the axle-bar E by means of the malleable casting D.

The axle-bar Eis arched upwardrat .E1 `to 'give space for the plow-beams.

I I are corner-brackets of malleable castiron, which embrace the knees of the axle-bar E at those parts where it is bent at right angles between the arch and the horizontal ends. Said castings are connected to the axle-bar by bolts or rivets 1". These corner-brackets have pivot-pins fi', which enter holes in the side bars of the bow-frame J, to whose rear bar J] the plow-beam K is connected. The pins t" form the fulcrums on which the frame J Works, the said frame forming a lever, by which the plow or plows are raised and lowered. The cornerbrackets I I are secured to the axle-bar by bolts or rivets, and serve not only for the connection of the frame or bail J, but also Serve to strengthen the axle at the knees'E The plow-beam K is connected to the leverframe J by the following device: M is a hinge, having oner plate secured to the straight rear bar J 1 of the frame J by clips m, the clip-bolts m1 holding the clips iirrnly in place upon the bar J l ofthe frame J. The clips may be transversely adjusted on the bar J1 by slackenn g the nuts m1. Another plow can be attached to the bar J1 beside the one shown.

The rear plate of hinge M is secured to the plow-beam K by a strap or clip, m2, which` passes over the beam, the construction being such that the beam can be adjusted backward and forward when the clip is loosened.

The lever-frame J has an arm, J2, extending in front of the fulcrunrpivots i', and connected by rigid link N to the shorter arm o of the an# gle-lever O. The construction is such that the backward movement of the lever lifts the plow-beam. The lever O is fulcrumed at (.ll upon the side of the tongue l?, and is moved beside a semicircular bar, Q, concentric with the fulcrum O', and notched at the upper edge for the engagement of the sliding spring-catch It, by which the lever is held in any position in which it may be placed.

The rear end of the tongue is secured to the arched part El ofthe axle-bar by a malleable cast-iron bracket-piece, S, made to lit the arch and the tongue, and secured thereto by its flanges and bybolts or rivets s. The front support of the tongue is a standard, T, whose lower end is secured to thefootbow or bar U. Therear' ends of the foot-bar U are secured to the arch El by means of the malleable cast-iron brackets or clips U1, made to it the arch E1 and bar U, and secured thereto by bolts or rivets u. At the front end of the bow is a foot-rest, U2, made of cast metal, and attached to the Wrought-iron bar or bow U. The seat is secured to the axle by a bracket-casting, W,- of malleable cast-iron. The bracket W is made to fit thetop ofthe arch El, and is fastened by bolts orrivets w. Between the seat and bracket is the` usual spring V.

I do not confine myself to malleable castiron as a material for the brackets or clips upon the wrought-iron axle E, as. other cast metal might be used; but I prefer malleable cast-iron, owing to its cheapne'ss and perfect adaptability to the purpose.

With the described construction I am' en abled to build ariding-plow strong, and cheap.

I claim as my inventionl. The arched axle E, in combination with which is' light',

the casting D, perforated plate G, axle-crank f Q tion for the frame J, all substantially as and for the purpose set forth.
